Coherent Debuts World's First Commercial 100 W Laser Bar At 808 nm

Santa Clara, CA - Coherent, Inc. has introduced the first Micro Channel Cooled Package (Onyx) diode laser bar to deliver 100 W (CW) of output power at 808 nm with high reliability. The specified lifetime is over 10,000 hours with an electrical to optical conversion efficiency approaching 60%. This water-cooled laser bar can be assembled into vertical stacks containing anywhere from 1 to 45 bars, with an industry leading pitch of 1.6 mm. This new Onyx MCCP 100 W diode laser bar can also be used to form compact horizontal arrays because each stack is only 11 mm wide, and can be placed directly next to another stack with less than 1 mm gap.

The primary application for the Onyx MCCP 100 W diode laser bar is as a pump light source for use in solid state lasers for medical and industrial applications. The higher power density reduces system cost because fewer bars are required to obtain a given output level. The high efficiency translates into less waste heat, thus reducing cooling and power supply requirements. The Onyx MCCP 100 W laser diode bar operates reliably in the hard pulsed mode often employed in solid state laser systems. This superior reliability is achieved through advances in packaging techniques and epitaxial structure, together with the use of hard solder construction.

Other important uses for this high power diode laser bar are as a direct source for various materials processing applications including cladding, welding, heat treating and brazing.
